Abstract

Students show deficient understanding on fraction division and supporting that understanding remains a challenge for mathematics educators. This article aims to describe primary students’ understanding of partitive fraction division (PFD) and explore ways to support their understanding through the use of sequenced fractions and context-related graphical representations. In a design-research study, forty-four primary students were involved in three cycles of teaching experiments. Students’ works, transcript of recorded classroom discussion, and field notes were retrospectively analyzed to examine the hypothetical learning trajectories. There are three main findings drawn from the teaching experiments. Firstly, context of the tasks, the context-related graphical representations, and the sequence of fractions used do support students’ understanding of PFD. Secondly, the understanding of non-unit rate problems did not support the students’ understanding of unit rate problems. Lastly, the students were incapable of determining symbolic representations from unit rate problems and linking the problems to fraction division problems. The last two results imply to rethink unit rate as part of a partitive division with fractions. Drawing upon the findings, four alternative ways are offered to support students’ understanding of PFD, i.e., the lesson could be starting from partitive whole number division to develop the notion of fair-sharing, strengthening the concept of unit in fraction and partitioning, choosing specific contexts with more relation to the graphical representations, and sequencing the fractions used, from a simple to advanced form.

Abstract

The service of recording and borrowing goods at the Teacher Learning Center agency is currently still being carried out manually. parties who will borrow goods must come to the teacher learning center directly and record borrowing data and item data is still done manually, whereas at this time it has entered the era of the industrial revolution 4.0, of course, everything will have efficiency and very fast access. With this problem, of course, the right solution is to have a system that can borrow and record goods based on a website. The process of creating and designing a website uses the Rapid Application Development model, which is a method that starts with the requirements planning stage, RAD design workshop (work with users, build system) and implementation. Testing on the application uses alpha and beta testing, alpha testing uses blackbox testing while for beta testing uses the mean opinion score (MOS). Alpha testing obtained the website running according to what was expected to be successful while beta testing obtained a measurement result score with 10 respondents, namely 88.60% based on alpha testing and beta testing, it was concluded that this website was able to meet and support the needs of users and agencies.

Abstract

Tingginya kasus tuberkulosis (TBC) menyebabkan sebagian pasien tidak patuh terhadap aturan minum obat yang berdampak pada ketidakefektifan pengobatan dan perburukan kondisi pasien. Penelitian ini bertujuan untuk menganalisis tingkat kepatuhan pasien TBC dalam meminum obat dengan mempertimbangkan dukungan dan keterlibatan Pendamping Minum Obat (PMO). Permasalahan utama yang dihadapi adalah belum tersedianya sistem dashboard yang dapat mengidentifikasi pola kepatuhan pasien secara sistematis, sehingga menyulitkan Dinas Kesehatan Provinsi NTB dalam menentukan pasien yang membutuhkan perhatian lebih. Penelitian ini menggunakan metode Prototyping untuk pengembangan sistem dengan cara bertahap. Selain itu, metode ini memungkinkan adaptasi cepat berdasarkan masukan dari Pengguna. Proses penelitian meliputi identifikasi kebutuhan, pengembangan Prototype, evaluasi Prototype, Coding System, pengujian dan evaluasi system. Penelitian ini berhasil mengembangkan Dashboard Pemantauan Kepatuhan Pengobatan TBC berbasis web yang interaktif. Sistem telah di uji kelayakan dengan pengujian Blackbox dan pengujian Mean Opinion Score (MOS) yang menghasilkan skor tinggi dengan hasil pengujian Admin/PMO sebesar 93,33% dan hasil pengujian Pasien dengan total 10 responden sebesar 96,33%, sehingga rata-rata kelayakan sistem secara keseluruhan yaitu sebesar 94,83%, yang menunjukkan antarmuka yang mudah dipahami dan memberikan pengalaman untuk pengguna

Abstract

The development of information technology has encouraged organizations to improve information management. However, the Association of Indonesian Academics and Scientists (ASASI) West Nusa Tenggara does not yet have an integrated web-based system for managing and presenting management member profiles. As a result, profile information is scattered, lacks structure, and is difficult for both internal members and the public to access. Additionally, management members have limited ability to independently manage and update their profile data. This study aims to design and implement an HTML-based frontend for a management member profiling system that enables both visualization and self-management of profile data. The system is developed using HTML, CSS, and PHP native without frontend frameworks or RESTful APIs to ensure simplicity, ease of maintenance, and suitability to organizational needs. The effectiveness of this approach is evaluated using usability, accessibility, and maintainability indicators, including ease of navigation, clarity of information presentation, and minimal dependency on external frameworks. The results show that the system successfully provides structured and user-friendly profile information while enabling efficient data management by users. The system improves transparency, enhances information dissemination, and supports more effective organizational management in the digital era.
